在配置文件里修改(android:theme="@android:style/Theme.NoTitleBar.Fullscreen"):
java代码：
  • <?xml version="1.0" encoding="utf-8"?>
  • <manifest xmlns:android="http://schemas.android.com/apk/res/android"
  • package="com.android.tutor"
  • android:versionCode="1"
  • android:versionName="1.0">
  • <application android:icon="@drawable/icon" android:label="@string/app_name">
  • <activity android:name="."
  • android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
  • android:label="@string/app_name">
  • <intent-filter>
  • <action android:name="android.intent.action.MAIN" />
  • <category android:name="android.intent.category.LAUNCHER" />
  • </intent-filter>
  • </activity>
  • </application>
  • <uses-sdk android:minSdkVersion="7" />
  • </manifest>
